Anthracite, generally known as white coal
or smokeless coal, will be the coal of maximum degree coalification. Its coal
content reaches high to 90 to 98 %, while hydrogen content material is
generally less than 4 %. It has numerous characteristics like low volatiles,
high strong coal, higher hardness, difficult abrasion, high fire point, shot
flame, weak chemical reaction, non-cohesiveness, no thickness of colloidal
layer and non-smoking when burning. The caloric value is roughly 6000 to 6500
kcal per kg. Occasionally, from the perspective of Anthracite Supplier, they contact
anthracite of fantastic volatile content material semi-anthracite and that of
small higher anthracite.
Anthracite is utilized in synthesis ammonia
manufacture as gas creating raw material and nitrogenous fertilizer production.
With properties of low ash, low sulfur and good abrasiveness, anthracite can
not only be utilized as fuel for blowing and sintering iron ore in blast
furnace but, especially for Calcined Anthracite as
raw material for manufacturing numerous carbon supplies like carbon electrode,
anode paste and activated coal. Some of superb quality may be manufactured into
briquette coal for aviation use for the objective of thermal insulation for
plane engine and car motor.
In detail, anthracite has following
applications as below.
Firstly, chemical material. Anthracite is
the important raw material for synthesizing ammonia and producing nitrogenous
fertilizer and urea. Those of low ash and low sulfur can nonetheless be
utilized to manufacture graphite as New Graphite Material.
Of course, apart from graphite, this sort of anthracite also has wide
application in creating calcium carbide, carbon electrode, silicon carbide,
carbon fiber and some other people.
Secondly, blast furnace injection coal.
With the every day enlargement of steel productivity and continuous improvement
and perfection of crucial technology in blast furnace coal injection, blast
furnace coal injection is playing a more and more important function in saving
smelting price in steel business. Anthracite becomes the very best option
within this application for very high carbon content. To use anthracite, some
within the type as Anthracite
Ball because the partial replacement of metallurgical coke, on 1
hand, decreases pig iron price by lowering iron and coke ratio, and on anther,
saves coking investment by developing much less coke oven. Therefore, it
decreases air pollution caused by coking simultaneously of significantly
relieving the intensive situation of coking coal resource.
Thirdly, electricity generation fuel.
Anthracite has already turn out to be superb fuel in electrical energy
generation for the characteristics of high heat and non-smoke in burning.
However, just as Coal
Supplier indicates, it is still not extensively applied only for the
purpose of relatively high cost. But with every day strengthened atmosphere
protection force, a batch of energy plants fueled by anthracite, merger lean
coal or perhaps the blender are put into production in succession. Anthracite
is certainly to be further popularized as electrical energy generation fuel.
